How to train memory?

In moments of desperation, when we can’t remember our credit card PIN for the life of us, it seems impossible. In reality, however, the capacity of our brains is enormous. It is estimated that the average brain has the capacity to store a staggering 2.5 million gigabytes of digital memory. But there’s a catch. We don’t just use it to store information. What’s more, memories are recorded differently in the brain than information in a computer, which remains as it was written. How can we remember better? And what are effective training techniques?
